AI Technical Summary

Benefits of technology

The invention relates to a lock system for a pile joint coupling system, which consists of lock housings and lock spindles. The locking pin is secured in a lock housing and the locking ring is positioned in a locking seat and receives the locking pin securely. The locking ring is discontinuous and has a groove in which it is installed. The locking pin has a recess for the locking ring and is held in place by friction. The holding capacity is not dependent on friction and the locking is durable and reliable provided the components of the coupling system are not broken. The locking system provides stability and durability to the pile joint coupling.

Problems solved by technology

When using a clamp for installation, a placement of the locking pin all the way to the bottom is somewhat difficult.

Embodiment Construction

[0026]The pile joint according to an embodiment of the invention, illustrated in FIG. 1, consists of a first concrete pile 1 having a first end 11 and of a second pile 2 connectible in an end-to-end manner to the first concrete pile and having a second end 21. The first concrete pile 1 has its first end 11 preferably provided with a first end plate 12, which may include sides 121 for an enhanced fitting of the end plate. Respectively, the second concrete pile 2 has its second end 21 preferably provided with a second end plate 22, which may include sides 221 for an enhanced fitting of the end plate. The plates with sides are also referred to as box shoes. The sides of the end plates are provided with apertures 3 for receiving locking pins 5 (described subsequently in more detail).

[0027]The pile joint comprises a coupling system 4 for connecting and locking concrete piles in an end-to-end manner relative to each other. The coupling system 4 comprises a lock housing 41 and a lock spind...

Abstract

The invention relates to a pile joint, which comprises a first concrete pile, a second concrete pile, and a coupling system therebetween for connecting and locking the concrete piles relative to each other. The coupling system includes a lock housing and a lock spindle connectible to each other and provided with transverse holes in such a way that the lock housing's transverse holes and the lock spindle's transverse hole settle substantially in line with each other for receiving a locking pin when the lock housing and the lock spindle are connected to each other. In addition, the lock housing is provided with a locking ring for retaining the locking pin in a position locking the lock housing and the lock spindle to each other. For ensuring the pipe joint's installation and durability there is in alignment with a first transverse hole of the lock housing a guidance pipe and in alignment with a second transverse hole of the lock housing, opposite to its first hole, a locking seat closed at one end and intended for the locking ring. The locking ring is adapted to be movable in a groove included in the locking seat and the locking pin is provided with a recess in the lengthwise direction of the locking pin to receive the locking ring.

Description

[0001]The invention relates to a pile joint, which comprises a first concrete pile, a second concrete pile, and a coupling system therebetween for connecting and locking the concrete piles relative to each other, or which comprises a concrete pile, a rock point, and a coupling system therebetween for connecting and locking the concrete pile and the rock point relative to each other, said coupling system including a lock housing and a lock spindle connectible to each other, said lock housing and lock spindle being provided with transverse holes in such a way that the lock housing's transverse holes and the lock spindle's transverse hole settle substantially in line with each other for receiving a locking pin when the lock housing and the lock spindle are connected to each other, the lock housing being provided with a locking ring for retaining the locking pin in a position locking the lock housing and the lock spindle to each other according to the pre-characterizing portion of claim...
